Special Issue Information

Dear Colleagues,

The irradiation of metallic materials by energetic particles (e.g., ions, neutrons, protons, or electrons) is frequently encountered in many applications, such as nuclear power systems, electron- or ion-based characterization techniques, and aerospace-oriented devices. Irradiation usually comes with undesired damages in the form of defect accumulation and physical property degradation. In general, the resulting damage effects are strongly dependent on the material microstructure and composition, as well as the radiation conditions. This Special Issue aims to present the latest experiments and simulations that can advance our understanding of the fundamentals of radiation damages in conventional or advanced metallic materials. We are inviting researchers in relevant fields to submit their original work to this Special Issue. We encourage submissions covering a wide range of topics, including, but not limited to, radiation-induced point defects and defect clusters, diffusion and segregation, hardening, volume swelling and surface modification, radiation-enhanced precipitation, recrystallization and grain growth, etc.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Radiation hardening is studied for stainless austenitic and ferritic-martensitic chromium steels after ion and neutron irradiation at various temperatures. Austenitic and ferritic-martensitic steels irradiated up to 30 dpa in various nuclear reactors and ion accelerators are studied at various temperatures. A change in Vickers microhardness is used as the radiation hardening parameter. A methodology is developed that allows one to determine the ion irradiation parameters, which ensure the radiation hardening of ferritic-martensitic and austenitic steels, as close as possible to the radiation hardening of the same steels under neutron irradiation. A transferability function is introduced to connect the irradiation temperatures for ion and neutron irradiation that provides the same radiation hardening. On the basis of the obtained experimental data, after ion and neutron irradiation the transferability functions are determined for the investigated austenitic and ferritic-martensitic steels, which connect the temperatures for ion and neutron irradiation and provide the same radiation hardening at a given damage dose.
